Final answer:
The cut in pressure is the lower threshold for a compressor to start, and the cut out pressure is the point it stops. These values vary by application and are vital for system efficiency and safety.
Step-by-step explanation:
The cut in and cut out pressure of a compressor, such as those under the Grovner brand (often associated with air compressors), refer to the pressure levels at which the compressor starts and stops to maintain the desired level of pressure within the system. The cut in pressure is the predetermined lower threshold at which the compressor will switch on to increase pressure.
Conversely, the cut out pressure is the higher threshold at which the compressor will turn off, having reached the desired pressure level in the tank or system. These pressure settings are crucial for the efficient operation of the compressor and to prevent over- or under-pressurization, which could lead to system damage or inefficient performance.
The exact values for these pressures can vary depending on the specific model and the application requirements. For example, a typical home air compressor might have a cut in pressure of around 90 psi (pounds per square inch) and a cut out pressure of about 125 psi. Industrial compressors or different brands may have different settings based on what they are being used for.
